A record 165,000 millionaires are forecast to relocate across borders in 2026, according to the Henley Private Wealth Migration Report — the largest movement of private wealth ever tracked, with more than 600 high-net-worth individuals changing their tax residency on every working day. Amid this great wealth migration, one micro-state continues to punch far above its weight: Monaco, where over 40% of residents are millionaires, the highest density on earth. As the UK, France and other high-tax jurisdictions push capital out, the principality’s zero-income-tax regime is drawing a fresh wave of HNWI interest in 2026.

Key Takeaways
- Henley & Partners forecasts a record 165,000 millionaire relocations in 2026, up from 142,000 in 2025.
- Monaco has the world’s highest millionaire density, with roughly 12,000 of 39,000 residents holding seven-figure wealth.
- The principality levies no personal income tax, no capital gains tax and no wealth tax for non-French nationals.
- Prime Monaco real estate averages around €57,569 per square metre, with Mareterra and Carré d’Or exceeding €100,000.
- Residency typically requires a Monegasque bank deposit of about €500,000 and a genuine local lease or purchase.
Why Monaco, and Why Now
The 2026 surge in wealth migration has clear push factors. For the first time in a decade Henley & Partners projects the United Kingdom as the largest single source of millionaire outflows, losing some 16,500 in 2025 after the abolition of non-domiciled tax status in April 2025. France’s wealth and succession taxes continue to nudge fortunes south. Monaco, a 30-minute drive from the French Riviera’s airports, offers proximity to Europe without the fiscal drag — a combination that explains why Knight Frank expects the principality to count roughly 16,100 millionaires by 2026.
The Real Estate Reality
Monaco remains the most expensive residential market in the world. Average prices sit near €57,569 per square metre, but in ultra-prime districts the numbers climb steeply: the new Mareterra land-reclamation district and the historic Carré d’Or transact beyond €100,000 per square metre, with exceptional Larvotto sales reported above €120,000. Knight Frank forecasts roughly 4% capital growth for 2026. For HNWIs, property is not merely a lifestyle purchase — a “proportionate” residence is a precondition of the residency application itself.
What This Means for HNWIs
Monaco rewards those who treat relocation as a structured exercise rather than a lifestyle whim. Securing residency generally means depositing around €500,000 (often €1 million-plus depending on profile) with a Monegasque bank and signing a genuine residential lease. The tax upside is substantial for non-French nationals, but it does not erase home-country exit taxes or reporting obligations, which must be planned for in advance. As with broader strategies around tax incentives for high-net-worth individuals, the value lies in sequencing the move correctly across jurisdictions.
Country Comparison
Monaco is not the only winner of the 2026 migration. The UAE remains the single largest beneficiary, its millionaire population up 98% over the decade and Dubai forecast to add more than 7,000 millionaires and $7 billion in new capital this year. Switzerland’s lump-sum “forfait” taxation appeals to those wanting Alpine stability and predictable, negotiated tax bills. Monaco’s edge is absolute zero on income, capital gains and wealth — but its scarcity of housing and high entry cost make the UAE and Switzerland more practical for many. The right hub depends on family base, business interests and citizenship.
Risks and Considerations
Monaco’s exclusivity is also its constraint. Housing supply is severely limited, pushing entry costs to the world’s highest and making the market sensitive to global liquidity. French nationals gain no income-tax benefit under the 1963 Franco-Monegasque Convention. Residency must be genuinely maintained — minimum presence and substance requirements apply — and tightening international transparency rules mean nominal moves no longer suffice. Relocating without coordinated cross-border tax advice can trigger exit charges that erode the very benefit being pursued.
The Bottom Line
With wealth migration hitting record highs in 2026, Monaco’s combination of zero income tax, security and prestige keeps it near the top of the HNWI relocation shortlist. But its scarcity and cost mean it rewards careful structuring over impulse — the principality is a destination to plan for, not to stumble into.
